The boost gauge will tell you if you have a vacuum leak which sounds like you do. Try spraying brake clean on all areas that has vacuum and if the idle changes, you'll narrow it down.

ok cool thanks Eric. Im taking my bumper off and checking every boost/vacuum leak this weekend. changing my plugs, cleaning my maf and iacv..... and if all that still does not help, im bringing it up to granite state dyno next week to have them fix the damn thing/possible tune and nistronic. Sick of this thing running like ****.

Start with the cheapest/easiest things to do and go from there. You're probably going to want a decent boost gauge at some point though if that one is unusable.

Haha usually the basic advice is the last thing you did that made it break but that doesn't exactly sound like it here...

yeah its strange last I looked to make it worse was a boost leak, so maybe i pulled an intercooler pipe to hard or something causing a much larger leak. The car is low, and cant get in my driveway so im going to take my bumper off pull it in and all the intercooler parts are right there. make sure everything is tight new plugs and go from there.

Id check to make sure there is clearance between the IC piping and the typical hole locations specifically by the battery tray. i had an incident where the cut edge made a 2in long slice right thru the pipe and it ran like garbage til i found it. Also had several cracked couplers over the years. And even a cheap ****ty boost gauge will show you what you need to know, as long as it also shows vac.
